Abstract

Summary

When evaluating the capability of any Airborne Gravity Gradiometer (AGG) system some of the most useful inputs are data collected over areas with good-quality ground truth. A gravity test range has been established at Kauring in Western Australia for such comparisons.

CGG (then Fugro Airborne Surveys) flew the fixed-wing FALCON AGG system over the Kauring AGG Test Site over three periods in July 2011, November 2011 and February 2012.

Comparison between the FALCON AGG survey data and the high resolution ground gravity data over the Kauring AGG Test site indicates that the FALCON vertical gravity, gD, has an error of +/- 0.18 mGal, and that the FALCON vertical gravity gradient GDD has an error of +/- 5.6 eotvos at 300m full wavelength low-pass filtering.

Analysis of repeat surveying over the Kauring AGG Test site suggest slightly lower errors of the order of +/- 0.10 mGal for the FALCON vertical gravity, gD; and that the FALCON vertical gravity gradient GDD has an error of +/- 4.7 eotvos after 300m full wavelength low-pass filtering.

We strongly recommend the collection and publication of comparative analyses over Kauring and areas with similar quality ground gravity data to establish the capability of AGG systems.
